Forbes calls it "The E-Mail Time Capsule," but it sounds more like sending a message in a bottle to yourself. It's very intriguing. What would you tell yourself 20 years from now?

Some of us will probably still be essentially the same, but most would have changed in many different ways. What do you like about yourself now? What would you like to change? Do you even want to find out? =)

You can opt to send the email to yourself after 1, 3, 5, 10 or 20 years. But you have to do it now. The offer ends today, November 30.
